Fans laid flowers on the club's pitch as they waited for official news about the fate of owner Vichai Srivaddhanaprabha, whose helicopter crashed outside the ground.

Emotional fans cried and embraced each other, while players tweeted their condolences on Sunday after local media reported that Srivaddhanaprabha had been on board.

There has still not been official confirmation of who was on board the helicopter belonging to Srivaddhanaprabha which crashed shortly after taking off from the stadium on Saturday evening following a Premier League match.

Tributes flooded in for the owner, who took over in 2010 and helped Leicester claim their unlikely Premier League triumph in 2016.

"I know the whole Srivaddhanaprabha family and the father, and what he has done for Leicester is incredible," former Leicester and England manager Sven Goran Eriksson told BBC Radio 5 Live.

"He took the club from second division up to the first division, winning it, and made them a big Premier League club.

"When you know him as I do, and of course the whole team and all the staff, you know that he is a very, very generous man."

Other Premier League clubs' offered their support and thoughts via social media, as well as former players, including Gary Lineker and Peter Shilton.

"Thoughts are with everyone at Leicester City," Lineker wrote on Twitter. "A terrible tragedy. Heartbreaking."

So far, the rescuers have not given details of the number of victims, but there is little hope that the occupants of the helicopter could have survived.
